My favorite way to take kefir is in smoothies, I blend frozen berries with the kefir and add some sweetener, either stevia for calorie free or Sucanat for natural sweetness. Its really good with just a "twang" of sourness. A quick way to drink kefir is to add a little Maple syrup, Sucanat or stevia to it, add a dash of vanilla and sprinkle with cinnamon or nutmeg. I call this my kefirnog drink. If you can tolerate a little sweetener, it really improves the kefir. It doesn't take much to make a huge difference.

if honey is allowed in your diet, add that to the kefir. Pumpkin pie spice is also really nice, plus all the things that Hopinso listed. :)

You can make wonderful salad dressing with it - the honey-mustard dressing can use kefir instead of yogurt. Or cucumber dressing, what's called "raita" (not sure of spelling)

Blueberry smoothes are my favorite way to have it.

Look up recipes for Lassi, there are many different kinds of Lassi (there's a post on Lassi somewhere in this forum) such as a digestive lassi that uses carminitive/pungent spices and a sweet lassi or mango lassi -yum! All of them can be made with kefir/yogurt.
